Canadian study shows benefit of later school start times

“Later start times could help Canadian teens’ grades,” Science Daily reports. “Researchers found that students from schools that started earlier slept less, were less likely to meet the national sleep recommendations for their age, and were more often tired in the morning.”

Science Daily reports that a study published in the Journal of Sleep Research used “data covering 30,000 students from 362 schools across Canada, from a cross-national survey conducted every four years in more than 40 countries in collaboration with the World Health Organization.”

Start times in the Canadian schools ranged from around 8:00 to 9:30. “We found a strong association between later school start times and better sleep for teens,” says Prof. Frank Elgar, co-author of the study.
